*Images and text below from Amazon.com:Decepticons beware, because Grimlock is out to cause some major mayhem! This Grimlock warrior figure converts in 5 steps from robot mode to stomping T-Rex mode and back. Can his enemies handle what he's got? Not as long as you keep converting him back and forth! Transformers and all related characters are trademarks of Hasbro.

Grimlock is one of the members of "Team Bumblebee" who starts off as a Decepticon but eventually changes allegiance. He also serves as the powerhouse of the team despite his lack of any weaponry.

Packaging:
The "Robots in Disguise" Legion Class figures are packaged on blisters connected to a card. The bubbles are not the normal kind that extend outward. Instead, each is vacu-formed to fit the shape of the figure underneath. The card features the same artwork seen on the One Step Changer and Three Step Changer Grimlock packaging. Interestingly, the art features the character in his beast mode rather than his robot mode. The figure is in robot mode while the insert shows off the dinosaur form.

The back of the packaging has no tech specs information at all. The instructions are printed there and below that are disclaimers in multiple languages with a blurb for the "Robots in Disguise" app in the center. As packaging goes it's rather dull on the back, but looks great from the front. As a long time fan this bugs me, but honestly most kids are just going to toss away the packaging so I get the desire to not invest tons of money into the back of the card.

Robot Mode:
Grimlock is portrayed as the biggest and bulkiest of the Autobots in the cartoon so it's no surprise this figure looks kind of bulky despite its size. The entire upper body is nice and wide with some thick pieces on it including the shoulders, forearms and torso. His legs are a bit smaller relatively speaking, but that just enhances how big the upper part of the figure looks. This figure has some of the key details from the animation model including a head sculpt with small horns on top and a chest with what appear to be layers of armor on it. His overall shape echoes Grimlocks from other toy lines, especially with the arms formed from the beast mode legs and the torso formed from the lower body of the dinosaur mode.

Grimlock is cast in green and black plastic - the two primary colors of the character from the TV show. His paint applications are done up in gunmetal grey, gold and light blue. The gunmetal grey is the most heavily used color. You'll find it on his arm, chest and waist area. It's a beautiful color and I'm really glad they used it. The gold is used on his face, and the eyes are blue. Interestingly, I think the face may have been sculpted without a mouth to give him a "battle mask" appearance. Either that or the gold is layered on so thick it's covered up whatever mouth was there! Since Legion Sidewipe's mouth is covered by a "battle mask", I'm inclined to believe the former not the latter. The final deco touch is a large, scannable Autobot symbol on the left shoulder. It's a bit less intrusive there than say, on the chest but I do find myself wishing it was a tad smaller.

Grimlock has four points of articulation, the shoulders and the hips. His hands are designed to fit weapons such as those that came with the Legion Class figures from "Transformers Prime". While I do wish he included an accessory, he doesn't really have weapons in the show so it's not a huge shock.

Transformation to Beast Mode:

Swing the tail on the back up over the head.

Move the robot arms back.

Swing the lower legs back.

Push the panels from the lower legs and the thighs (now showing the beast mode head) together.

Swing the beast mode arms in place.

Beast Mode:
I mentioned in my previous Warrior Class Grimlock review that this Grimlock's beast mode seems to be partly inspired by the 1998 "Godzilla" design (which some call "GINO" Godzilla In Name Only). Part of this is due to the huge lower jaw on the beast mode head and the plates running along the back of the figure. This figure reinforces my opinion about his dinosaur form. It does have influences from G1 Grimlock since both are T-Rex based Dinobots, but in spirit this Grimlock feels different from his G1 counterpart.

The sculpting on this figure looks great, incorporating a lot of Grimlock's features from the show including his teeth, the "crown" design on his beast mode head and the circle of line details at the hip section of each leg. He even has small claws sculpted into the arms and feet. From a sculpting perspective I think he looks great.

This mode features a nice mix of the black and green colors. The black is concentrated on the central part of the body with the green on the outer parts like his head and tail. Silver and gold paint show on his head and in an impressive combination of sculpting and painting his beast mode eyes (with pupils sculpted in) are painted light blue. The top of the beast mode legs and the claws on his feet are painted gunmetal grey, helping to tie all the colors together nicely.

Like the robot mode, this mode features four points of articulation: the arms and the legs. The sides of his legs feature small holes which can accomodate weapons like the robot mode fists.

Final Thoughts:
This is a cute little figure. I love the concept of having "pocket size" representations of characters from a "Transformers" show and this Grimlock fits the bill. He's also nicely sculpted and I dig the colors used. Recommended for anyone who enjoys the Legion Class of figures.
